The windings '24 are connected acrossthe work circuit or lamps 3, 3 and in series therewith there is provideda second. carbon pile 27 operated by a lever 28 controlled by a coil 29also connected across the work circuit or lamps 3, 3. The coil 2%controls the carbon pile 28 so as to keep the voltage at the translatingdevices substantially constant, and this action is magnified by thevariations in the carbon pile resistance 27 which is-controlled by coil:29.

In operation the battery is arranged to feed the work circuit 3, 3 whenthe generator is not running or when its oltage is too low forpracticable operation thereunder. Under these conditions the switch 9closes the circuit 8, 8, thereby connecting the battery directly to thelamps, 3, 3, although the carbon pile resistance is included in circuitin order that the Voltage at the lamps may be maintained substantiallyconstant irrespective of changes in the battery voltage.

l'f now the speed of the main generator be increased so that it willproduce a volage sufficicnt to feed the lamps the coil T closes theswitch 6 and opens the switch 9. This connects the generator with thebat tery and work circuit and also throws the coil 20 in series with thebattery. When the voltage of the, generator rises sufiiciently toproduce the proper charging current for the battery this chargingcurrent be limited or maintained substantially constant by means of thecoil 20. That is, when such a charging current is produced the strengthof coil 20 is such that it acts upon the core 19 and, without raisingthe core, nevertheless puts it in a condition of equilibriurn. If thevoltage of the generator tends to increase, thereby tendin to increasethe charging current, the coil 20 will raise the core 19, therebyincreasing the resistance of the pile 13 and decreasing the generatorfield strength so that its voltage will be accordingly decreasedsuificiently to maintain'the charging current substantially constant. Ifa decrease in generator voltage occurs a reverse action takes place andthe coil 20 allows the core 19 to drop, thereby decreasing theresistance of the carbon pile 13 and increasing the voltage of thedynamo 1, so that the charging current may be brought back substantiallyto the same value. In describing the operation thus far we have assumedthat the switch 22 was open, thus disconnecting thework circuit,

so thatthe coil 21 S as deenergized. 1 v The operation t he describedcontinues until the battery becomes-properly charged.

When it has become suficiently charged, in-

dicated by its rise in voltage to a predetermined point, and thecorresponding-- rise of the generator voltage, theelectromagnet 17becomes suificient-lyencrgined to place its creased although maintainedsubstan core 16 in equilibrium. When voltage rises any iigher the coreis thereby increasing the resistance bon pile 12 and decreasing the go;voltage. This cuts down the ca. rent as will be clearly understood.,.Thus the solenoid 16, 1'? is not hrcught into action until the batteryhas become charged to the desired extent and it then prevent furtherincrease in generator vcltage and to decrease the battery chargingcurrent. It, therefore, usurps the functions of the variable resistance13 and the core readilydrops back to its initial posi' c due to thedecrease in the charging curr .1. go That is, when the battery isreceiving substantially constant char-gin e Voltage coil 1.? and core 16tially inoperative, a1

the

4 sum stantially inoperative. it is also noted the electro-inagnetsoperating upon th rho estate 12, 13 operate mechanically independent ofone another.

' It is desirable when the work circuit is being fed by the generatorthat the chargiug current to the battery be somewhat de- .r constantafter such decrease, in order that the generator may not be overloaded.For this purpose the coil 21 acts to aid the coil 20 and accordingly adjust its action depend ent upon the load being thrown on at the workcircuit by nsurping pert its i HEC '1 tions when the switch 22 isclosed. That is, upon the closing of the switch the coil 21 becomesenergized and produces a constant attractive force upon the core 19.This allows the generator voltage to be kept down with a much smallercharging current so that the total current supplied by the generator maynot be excessive. That is, when the work circuit is disconnected and thegeneratonrunning at a proper speed, it will furnish a substantiallyconstant charging current to the battery, which current is keptsubstantially constant by the coil 20. It, now, the work circuit beconnected and fed by the generator, the generator might be overload edby the additional work circuit load thereon. But in in improved system,upon this connecting yap of the pork circuit, the coil 21 is energ zed.so theta less current in coil :20 is required to reduce the pressure onthe pile '13 and govern thegene'rator volt age. Consequently, thecharging current to the battery is decrcased so that the generator isnot overloaded when the work circuit isv fed by the generator. I

- Although preferable, it is not necessary to the broad aspect of my im'irovernents that the coils 1?, 20 and 21 act directly upon therheostats l9. and 13, since their func time may obviously beaccomplished indithe 0mm 0f suim vlectro-maw nuc'ied famousto witage c 1enevntor am; arranged to me 0 :01
